IPC: H01R13/41
Filed: 1962-01-19
Abstract: 921,893. Punching; making lead-through connectors. BELLING & LEE Ltd. Jan. 19, 1962, No. 2009/62. Classes 83 (2) and 83 (4). A method of securing an insert surrounded by a sleeve in sheet material comprises positioning the sleeve on the sheet material with the insert projecting only from the end remote from the end of the sleeve in contact with the sheet, applying pressure to the sleeve and a complementary cutting action to the opposite face of the sheet to cause the sleeve to make its own aperture and be secured in the sheet and thereafter transferring the pressure to the projecting part of the insert to force at least a section of said projecting part into the sleeve. A sheet of material 1 rests on the cutting face 2 of a die 3. A sleeve 6 formed from resilient electrical insulating material rests on the sheet and the sleeve is moulded on to an insert comprising smooth-walled sections 8 and 9 separated by a barbed section 10. The sleeve is confined by a ring 11. A primary ram 14 acts on the sleeve to shear out a disc of material 15 from the sheet and force the insert into the place thereof. Simultaneously, or immediately thereafter a secondary ram 17 acts on the insert and forces it into the sleeve to the position shown in Fig. 2, where the barbed .portion causes the sleeve to expand at 18 and 19. Specification 776,373 is referred to.

Patent GB-1212734-A (GB)
Title: Improvements in or relating to underwater echo-sounding
IPC: G01S7/60
Filed: 1968-01-15
Abstract: 1,212,734. Echo-sounding. ELECTROACUSTIC G.m.b.H. 15 Jan., 1968 [14 Jan., 1967], No. 2232/68. Heading H4D. In an underwater echo-sounding system optimum resolution at both very short and very long ranges is obtained by transmitting, in each sounding period, at least two sounding pulses of different carrier frequency substantially simultaneously and by making the receiver responsive to the highest frequency for earlyarriving echoes and to the lowest frequency for late-arriving echoes. In the Fig. 5 embodiment contact 49 on the stylus-carrying belt 15 of an electrochemical echo recorder 43 bridges contacts 47, 48 to trigger pulse generators 22, 23 for emission of two frequencies simultaneously. Echoes received by tuned receivers 27, 44 and 28, 45 are passed via switch-tuned amplifier stage 40, doubletuned stage 41 and a final amplifier 42 to recorder 43. At the beginning of the sounding period, and for a time determined by the length of contact 46, transistor T 1  conducts to short part of L 3  and so tune stage 40 to the higher frequency; for the remainder of the sounding period T 1  is blocked and stage 40 is tuned to the lower frequency. Since attenuation increases with range, the energy content of the higher frequency (short range) sounding pulses can be made smaller than that of the lower frequency (long range) pulses by decreasing the pulse length and amplitude with increase in frequency; this permits better resolution at short range. Simultaneous transmission is ensured by differently delaying the transmission of frequencies other than the lowest frequency, such that the first amplitude peak in each pulse coincides with the first peak of the lowest frequency. If it is required to record a "white line" in the sea-bed contour the highest frequency may be transmitted a little before the other frequencies. In a second embodiment (Fig. 3, not shown) separate receiving channels are provided for two frequencies, the higher frequency channel being open for the whole sounding period and the lower frequency channel being open for the latter part only of the sounding period. Due to rapid attenuation of the higher transmitted frequency, echoes of this frequency are not of significant amplitude in the latter part of the sounding period, but if desired the higher frequency channel can be blocked in this latter period. The echo signals may be differentiated before being recorded. Modifications of the switched tuning of stage 40 in Fig. 5 are described, examples of carrier frequencies and pulse lengths are given, and the electrochemical recorder may be replaced by a cathode - ray tube indicator.

Abstract: 494,872. Type-bar-making machines. MERGENTHALER LINOTYPE CO. Jan. 25, 1938, No. 2359. Convention date, April 28, 1937. [Class 100 (iii)] Distributing matrices.-Machines having a column of magazines, which is movable to bring different pairs thereof into operative position, are provided with a fount-selector having automatic means for adjusting it as different pairs of magazines are moved into operative position, such automatic means being themselves adjustable, so as to vary the position to which they will move the fount-selector in accordance with variation in the founts carried by the magazines. Fountrejecting means are also provided for preventing the passage of any matrices not appropriate to either magazine of the pair in use. The matrices to be distributed are fed to an upper distributer U, Fig. 1, which is provided with an adjustable bridge U<6>, Fig. 6, to co-operate with notches in the feet of the matrices. Matrices unprovided with a notch that registers with the bridge are supported at a higher level, and engage the bar of the upper distributer, by which they are delivered to the lower magazine of the pair. Matrices having a notch that registers with the bridge fail to engage the upper distributer-bar, and fall down a shoot U<9> leading to the distributer U<1> of the upper magazine. A fount-distinguisher, for rejecting matrices not appropriate to either magazine, comprises a rib U<11>, Fig. 5, located in the upper distributer-box just in advance of the matrix-lifter. Fountdistinguishing notches are located in the same position on matrices of a pair of founts, and matrices having notches which do not register with the rib are arrested thereby, and the distributer is stopped. The fountselecting bridge U<6> is carried by a slide U<12>, and is adjusted against spring pressure by a lever U<14>. The fount-distinguishing rib U<11> is similarly adjusted by a second lever U<24>. The levers are operated, as the magazines move, by either of two pairs of stepped discs V, V<1> and V<2>, V<3>, which are associated with the upper and lower pairs of magazines respectively. The discs are angularly adjusted by hand into such positions that, when they come into action, they locate both the fountselecting bridge and the fount-distinguishing rib in positions appropriate to the founts contained in the magazines. Each disc has two sets of steps designed for use with existing matrices, which have either a fount-distinguishing notch located in one of twelve different positions, or a fount-selecting notch located in one of eight different positions. A second notch is cut in the matrices, where required, to enable them to co-operate with both the fount-selecting bridge and the fount-distinguishing rib. Specification 445,899 is referred to.
